[0053] As Figures 3-5As shown, the application provides a vehicle lamp module, which has a longitudinal axis extending along the x direction and along the light emitting direction, a transverse axis extending along the y direction, and a vertical axis extending along the z direction in a Cartesian coordinate system; the vehicle lamp module comprises a light source 20, a primary optical element 10, and a secondary optical element 30 arranged in sequence along the longitudinal axis; the vehicle lamp module is provided with a light-shielding fixed support 50 at the periphery, and the light source 20 is provided with a heat sink 60 away from the primary optical element 10; the circuit board of the light source 20 is fixed to the heat sink 60, and the heat sink 60 is used for dissipating heat for the vehicle lamp module in the working state.

[0054] The light emitting surface 12 of the primary optical element 10 protrudes away from the light source 20, and comprises a first light emitting curved surface 121 and a second light emitting curved surface 122 arranged in sequence and connected along the extension direction of the vertical axis, and the first light emitting curved surface 121 and the second light emitting curved surface 122 are bounded by the light emitting optical axis of the light source 20;

[0055] Wherein, along the vertical axis and gradually away from the second light emitting curved surface 122, the first light emitting curved surface 121 comprises a variable-curvature light adjusting surface I 121a and a variable-curvature light adjusting surface II 121b arranged in sequence; and along the vertical axis and gradually away from the second light emitting curved surface 122, the angle between the tangent plane of the variable-curvature light adjusting surface I 121a and the x-y plane gradually decreases from 76° to 60°, and the angle between the tangent plane of the variable-curvature light adjusting surface II 121b and the x-y plane gradually decreases from 60° to 30°;

[0056] The secondary optical element 30 is arranged close to the light emitting surface 12 of the primary optical element 10, and is used for collimating the light entering the secondary optical element 30 again, and the light emitting side of the secondary optical element 30 is provided with a plurality of pattern units 311.

[0057] Specifically, the variable-curvature light adjusting surface I 121a collimates the light close to the middle part of the primary optical element 10, and the angle between the tangent plane of the variable-curvature light adjusting surface I 121a and the x-y plane gradually decreases from 76° to 60°, so that the light in the upper middle part converges more to the upper middle part of the pixel, the energy is concentrated, and the light in the upper middle part of the pixel is more concentrated. Figure 14 (a) In the traditional scheme, the light in the upper middle part is dispersed, the brightness is dark, and in the embodiment Figure 14 (b) The brightness of the upper middle part of the single pixel is stronger, the light deviating from the central area is less, the pixel edge is sharper, and the aberration and dispersion of the periphery of the upper middle part of the pixel are weakened.

[0058] The angle between the tangent plane of the variable-curvature light-adjusting surface II 121b and the x-y plane gradually decreases from 60° to 30°, the variable-curvature light-adjusting surface II 121b refracts the light close to the upper edge of the first optical component 10 to the upper oblique direction, so that the light is adjusted to be divergent to the upper direction and does not enter the second optical component 30, thereby reducing the energy distribution of the edge of the final presented single pixel, and Figure 14 (b) can be seen, compared with Figure 14 (a), the upper edge lighting area range is smaller, and the aberration of the upper edge is obviously weakened; meanwhile, it is beneficial to reduce the light emission angle, and Figure 14 (b) can be seen, compared with the traditional scheme, the upper edge of the present application Figure 14 (b) is significantly lighter, and the dispersion is improved.

[0059] The second optical component 30 collimates the light collimated by the first optical component 10 again, so that the final emitted light is close to parallel light. Referring to Figure 11 , the light-emitting side of the second optical component 30 includes a plurality of pattern units 311 arranged in an array, the arch height of the pattern unit 311 is greater than 0 and less than or equal to 0.1 mm, and is used to adjust the divergence angle of the emitted light in the transverse direction (the angle between the two emitted light rays from the light-emitting side 33 of the second optical component 30 in (b)) to be limited between 0.5°-3°, so as to realize the constraint control of the divergence angle (reduce the dispersion) and the energy distribution, the surface shape of the single pixel in the transverse direction. When the arch height of the pattern unit 311 is equal to 0, the energy distribution of the light is too large, the boundary of the single pixel is sharp, the connection of the adjacent pixels is poor, and even there is a dark gap between the adjacent pixels; when the arch height of the pattern unit 311 is greater than 0.1 mm, the constraint on the energy distribution is weak, and the effect of improving the aberration and the dispersion is not obvious. Figure 13 It is worth noting that the arch height of the pattern unit 311 refers to the maximum size of the surface of the single pattern unit 311 protruding from the reference surface of the light-emitting side 33 where the pattern unit 311 is located.

[0060] In other embodiments, the angle between the tangent plane of the variable-curvature light-adjusting surface I 121a and the x-y plane gradually decreases from an angle greater than 60° to 60° along the vertical axis and in the direction gradually away from the second light-emitting curved surface 122, and the maximum angle can reach 90°. In this embodiment, the middle-upper light can be converged to the middle of the pixel, and the aberration and dispersion of the middle-upper periphery of the pixel can be controlled, but the brightness of the middle-upper region of the single pixel formed by projection is not as large as that when the maximum angle is 76° in the previous embodiment, and the light deviating from the central region is relatively more.

[0061] Referring to

[0062] Figure 9 ​The second light-exiting curved surface 122 includes a spherical surface segment 122a and an arc surface segment 122b, the spherical surface segment 122a and the arc surface segment 122b are sequentially arranged in the direction along the vertical axis and gradually away from the first light-exiting curved surface 121, the curvature radius R of the spherical surface segment 122a is 1.5mm-2.0mm, and the included angle between the tangent plane of the arc surface segment 122b and the x-y plane is 25°-35°.

[0063] Specifically, taking the curvature radius R of the spherical surface segment 122a as 1.5mm and the included angle between the tangent plane of the arc surface segment 122b and the x-y plane as 30° as an example, the spherical surface segment 122a and the arc surface segment 122b can collimate the light rays close to the middle part of the first optical component 10, so that more light rays in the lower part converge towards the middle part of the pixel, the energy is concentrated, and the light rays deviating from the central region are less, and the edge of the middle and lower part of the pixel is sharper, which is beneficial to reduce the aberration of the periphery of the middle and lower part of the pixel. Figure 14 As shown in (a), the light rays in the lower part of the traditional scheme are dispersed, and the brightness is uneven, and as shown in (b), the brightness of the middle and lower part of the single pixel is more concentrated, and the light rays deviating from the central region are less, and the edge of the middle and lower part of the pixel is sharper, which is beneficial to reduce the aberration of the periphery of the middle and lower part of the pixel. Figure 14 As shown in (a), the lower edge of the traditional scheme is obviously blue, and the chromatic dispersion is obvious, compared with the traditional scheme, the present application Figure 14 As shown in (b), the lower edge of the present application is light yellow, and the chromatic dispersion is improved. Figure 14

[0064] The curvature radius R of the spherical surface segment 122a of the present application can also be 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, and the included angle between the tangent plane of the arc surface segment 122b and the x-y plane can also be 27°, 29°, 31°, 33°, 35°, etc., which is not limited herein.

[0065] Reference Figure 11 The lateral diffusion coefficient of the pattern unit 311 is (-2, 2), and the size in the extension direction along the lateral axis (y direction) is 2mm-3mm; the vertical diffusion coefficient is (0, -1.6), and the size in the extension direction along the vertical axis (z direction) is 2.5mm-3.5mm.

[0066] The diffusion coefficient is a commonly used optical design parameter in the optical design simulation software Lucidshape, which determines the distribution angle of the lens surface light rays, and LucidShape is a computer-aided design software widely used in the optical design industry for the design and simulation of lighting and optical products. By adjusting the diffusion coefficient of the reduced pattern unit 311, the present application can reduce the exit angle of the light rays emitted from the single pattern unit 311, effectively reduce the chromatic dispersion of the single pixel boundary corresponding to the single pattern unit 311, and optimize the optical effect of the single pixel and the overall pattern.

[0067] ​And, by controlling the lateral size of the pattern unit 311 to range from 2 mm to 3 mm and the vertical size to range from 2.5 mm to 3.5 mm, the energy distribution of the single pixel corresponding to the single pattern unit 311 in the lateral and vertical directions can be controlled and constrained, and in the Figure 15 In (a), the lateral size of the single pixel of the projection pattern of the conventional scheme near the side edge is large and more light rays deviate from the central region, while in the present application Figure 15 The size of the single pixel of the projection pattern of (b) near the side edge is smaller, and especially the deviation of the light rays in the extending direction of the lateral axis (y direction) is less, so that the surface deformation of the single pixel of the projection pattern near the side edge is controlled, and the imaging quality of the projection pattern near the side edge is improved.

[0068] Referring to Figure 13 The projection of the light exit surface 12 of the primary optical component 10 on the x-y plane is an arc-shaped surface with the middle part bending towards the side of the light source 20, and the diameter D of the arc-shaped surface is 400 mm to 500 mm. In the present embodiment, the diameter D is taken as 450 mm, and by designing the arc of the light exit surface 12 of the primary optical component 10, the distance between every two adjacent pixels in the lateral direction can be made closer, which is beneficial to the connection between the adjacent pixels and the formation of a complete light pattern, and at the same time, the energy distribution and the diffusion angle of the pixel in the lateral axis direction can be adjusted and constrained.

[0069] Of course, the diameter D of the arc-shaped surface of the present application can also be 450 mm, 460 mm, 470 mm, 480 mm, 490 mm, 500 mm, etc., which is not limited herein.

[0070] Referring to Figure 13 The middle part of the light entrance side 32 of the secondary optical component 30 protrudes towards the side close to the light source 20, the middle part of the light exit side 33 of the secondary optical component 30 protrudes towards the side away from the light source 20, and the curvature of the light entrance side 32 is smaller than that of the light exit side 33; specifically, the curvature radius r1 of the light entrance side 32 is 250 mm to 300 mm, and the curvature radius r2 of the light exit side 33 is 50 mm to 55 mm.

[0071] In the process of optical system design, under the condition of given focal length and lens opening size, the deflection angle of light rays in the entire system is a fixed value. If the light entrance side 32 of the secondary optical component 30 is a plane, the light exit side 33 needs to be designed with a very large curvature. The large curvature of the light exit side 33 on one side will cause the deflection of light rays on this surface to be too severe, and a great aberration will occur near the side edge of the secondary optical component 30.

[0072] For example, the curvature radius r1 of the curved surface of the light-in side 32 is 250 mm, and the curvature radius r2 of the curved surface of the light-out side 33 is 53 mm. In this embodiment, to reduce aberration, the secondary optical element 30 does not adopt the traditional plano-convex lens design, but the light-in side 32 and the light-out side 33 both adopt curved surface design, and the curvature of each side is not large, so that the incidence angle / emergence angle of the light on each surface of the light-in side 32 and the light-out side 33 is not large (not using a single side to deflect the light too much), so that the overall aberration of the secondary optical element 30 is reduced. On the other hand, since the collimation effect of the primary optical element 10 on the light is limited, the light path after collimation by the primary optical element 10 is not completely parallel to the x direction, so the incidence angle of the light contacting the surface of the light-in side 32 is large, and Fresnel reflection is likely to occur, and the light cannot enter the secondary optical element 30 and be effectively utilized. Therefore, the curvature of the light-in side 32 is designed to be smaller than the curvature of the light-out side 33. The small curvature of the light-in side 32 can avoid the incidence angle of the light hitting the surface of the light-in side 32 being too large to cause Fresnel reflection, thereby avoiding the loss of light caused by Fresnel reflection, while reducing aberration and ensuring the brightness of the projected pattern.

[0073] Of course, the curvature radius r1 of the light-in side 32 of the present application can also be 260 mm, 270 mm, 280 mm, 290 mm, 300 mm, etc., and the curvature radius r2 of the light-out side 33 can also be 50 mm, 51 mm, 52 mm, 54 mm, 55 mm, etc.

[0074] Reference Figure 12 The vehicle lamp module further comprises a positioning bracket 40.

[0075] The light-out surface 12 further comprises a positioning and connecting injection molding surface 123, which is located on the side of the first light-out curved surface 121 away from the second light-out curved surface 122 and is connected with the first light-out curved surface 121.

[0076] The positioning bracket 40 covers the primary optical element 10 from the side of the primary optical element 10 away from the light source 20, and the positioning bracket 40 is connected with the positioning and connecting injection molding surface 123.

[0077] In the construction, the positioning support 40 and the first optical component 10 are made by twice injection molding, specifically, the positioning support 40 is formed first, and then the first optical component 10 is secondarily injection molded in the cavity of the positioning support 40, and the positioning connection injection surface 123 is connected with the positioning support 40 after the solidification of the first optical component 10. During the solidification process of the first optical component 10, the edge of the first optical component 10 will be cooled and shrunk, if the positioning connection injection surface 123 is not arranged, the positioning support 40 will be directly contacted with the first light-emitting curved surface 121 of the edge of the first optical component 10, and the first light-emitting curved surface 121 will be deformed during the solidification and cooling shrinkage, and the expected effect of eliminating aberration or dispersion cannot be achieved, and even the light-emitting projection pattern will be seriously deformed.

[0078] In the embodiment, the positioning support 40 covers the first optical component 10 and is connected with the positioning connection injection surface 123, so that the first optical component 10 can be fixed and the problem of unstable light type caused by the shaking of the first optical component 10 can be avoided.

[0079] The terms mentioned in the present application are explained as follows, the pixel refers to the smallest division unit of the projection pattern of the optical module, that is, the projection pattern is composed of multiple pixels; the dispersion refers to the difference phenomenon between the color of the boundary of a single pixel and the color of the pixel itself; and the aberration refers to the phenomenon that the pixels at the periphery of the projection pattern are deformed and deviated from the optical axis due to the relatively dispersed distribution of the projection light energy on the projection surface.

[0080] As shown in Figure 4 , Figure 12 , the space coordinate axis with the light-emitting center of the light source 20 as the coordinate origin o is shown; wherein the direction of the vertical axis is parallel to the z direction in Figure 12 , the longitudinal direction of the arrangement of the components in sequence from the light source is parallel to the x direction, and the direction of the transverse axis is parallel to the y direction in Figure 12 . When arranged in the manner of Figure 12 , the horizontal plane is parallel to the x-y plane.

[0081] Referring to Figure 11 , the pattern unit 311 is rectangular, diamond-shaped or circular.

[0082] The multiple pattern units 311 arranged in the lens surface array can respectively reshape the LED emitted light from multiple positions of the lens surface, and limit and narrow the transverse emission diffusion angle of the light at each part of the lens surface, so that the finally emitted light forms parallel light, which is beneficial to achieve better dispersion elimination effect;

[0083] And, the multiple pattern units 311 arranged in the lens surface array can control the lateral change of the surface shape respectively, and can control the diffusion angle and energy distribution of each single pixel of the LED emitted light in the horizontal direction from the multiple positions of the lens surface respectively, so as to eliminate the lateral aberration, weaken the lateral deformation of the pixels at the side edge of the secondary optical element 30, and improve the imaging quality of the pixels at the lateral edge of the secondary optical element 30.

[0084] Reference Figure 11 The arch height of the pattern unit 311 is 0.1 mm. The actual test proves that when the arch height of the pattern unit 311 is 0.1 mm, the lens light emitting surface 12 can limit the diffusion angle of the emitted light in the lateral direction to the minimum, realize the strongest constraint control of the energy distribution of the single pixel in the x direction, further eliminate the lateral edge aberration, eliminate the lateral deformation of the pixels at the side edge of the secondary optical element 30, and the imaging quality of the pixels at the lateral edge of the secondary optical element 30 reaches the best.

[0085] The application also provides a vehicle, which comprises the vehicle lamp module. The vehicle of the application includes a motor vehicle, a non-motor vehicle and other vehicles, and does not limit the specific type of the vehicle.
